Another purpose is tojprovide, in a cot mits the' revolubleehopper tok"bevoorreton chopper, means operatively connecting the drive axle of themachine and the'y revoluble chopperfor the kpurpose of trans-v mittingmotion tothe latter without interhe vertical. adjustability of thechopper. l

Still another Vpurpose isy tol provide va frame of simple, efficient andpracticaljconstruction .for supporting the chopper shaft and.itsconnections with the drive axle, the frame being compact, durableVand in such design andzjp'roportions as v-to enable the means forvadjusting a portion of the chop, per shaft tov be conveniently-locatedina position topermit'of ready access thereto-by the operator. y I

The section 31 of theshaft 25 carries a revoluble chopper 33 whichcomprises a disk 34 fastened at 35 in any suitable manner to the end ofthe'section 31 of the shaft 25. A.

plurality of arms 36 are carried by the disk and these, in turn, carrythe cutters 37. A segment rack 38 is supported upon the frame l, thereheilig a lever 39 mounted on a shaft 40 in the lower end of the rack.The shaft is in bearings of the under part of the frame l and projectingradially from the,

1 links 42 are pivotally conucctedat 442". The

links are brought together forwardly of the arms 4l and upwardly and arefastened together as shown. The links are also, in turn, adjustablyconnected in' a slotted enlargement of the under part of the section 28of the shaft housing 26, as at 43. rl `he connection 43 includes a slidein the slotted enlargement, said slide being pivotally connected at 43hto the joined upper ends of the links 42, so that when the links 42 aremoved upwardly or downwardly, the section 28.0f the shaft housing 2G maybe moved upwardly and downwardly on its runiversal joint. Thisconnection is capable of adjustment so as to regulate or render therange of adjustment of the shaft housing section 28 variable. Theconnection 43 can be set in the slot in order to obtain said result.

The lever 39 has a conventional hand grip controlled dog for cooperatimgwith the teeth of the rack for the purpose of holding the lever indifferent positions according to the adjustment of the section 28 of theshaft housing 26.

The section 28 of the shaft housing` 26 carries two grease cups 44, oneimmediately adjacent the universal joint of said casing, the other inclose proximity to the disk of the chopper, for the purpose oflubricating the shaft 25.

The cutters of the chopper are of such curvature that, as the chopperrotates, they willV remove the tops of the cotton plants and, due to theuniversal adjustment of the shaft casing 26, the cutters can be adjusted1 according to the heights of the plants.

The invention having been set forth, what is claimed is:

In a cotton chopper, a frame, an axle and axle casing mounted in saidframe, the axle including supporting wheels, said axle casing includinga differential housing provided with a rearwardly extending shaftVhousing, a shaft in said shaft housing andl have oscillating movementsupwardly andV downwardly, a support carried by the axle casing andconnected to the casing of the universal joint of the second shafthousing, the oscillating section ofthesecond shaft extending forwardlyand provided with a relatively large revoluble chopper on its forwardend, links pivotallyconnected to ex tensions of said supportandextending forwardly and upwardly and having' a 'sliding connectionwith the housing of the upwardly and downwardly movable section ofthefirst shaft, manually operated means .on the frame and provided with aslot and pin connection with the linksV for moving the links and therebyimparting upwardand downward movements to the movable section of thesecond shaft, and means for holding` the manually operated means indifferent pcsitions,

In testimony whereof he aiiixes hissiguature.
